AI generates periodised training plans based on your goals and availability

The platform asks about your target event (or general fitness), current ability level, and how many sessions per week you can commit to. Its algorithm then builds a multi-week plan with progressive overload, mixing endurance, speed, and technique sets. Plans adjust automatically if you miss sessions or input slower times.

Business outcome: Athletes receive a structured, science-backed training schedule without paying for a human coach.

Automatic workout logging via wearable and manual entry

iSWIM syncs with Apple Watch and other swim-tracking wearables to log distance, pace, stroke count, and heart rate. For swimmers without a smartwatch, the app includes a manual timer and interval tracker. All data feeds back into the AI to refine future recommendations.

Business outcome: Accurate performance data collection with zero manual effort, enabling data-driven training adjustments.

Workout difficulty adjusts based on your recent performance trends

If you consistently hit faster paces than predicted, the AI increases the intensity of future sessions. If you are struggling, it dials back volume or adds more rest intervals. This prevents both overtraining and stagnation.

Business outcome: Training load stays in the optimal zone for improvement, reducing injury risk and plateaus.

Stroke rate and efficiency metrics from wearable data

For users with compatible wearables, iSWIM analyses stroke rate, distance per stroke, and SWOLF (swim golf) scores. These metrics help identify inefficiencies in your technique, such as slipping in the water or an uneven stroke rhythm.

Business outcome: Swimmers get actionable data on their swimming efficiency, not just pace and distance.

Library of 500+ pre-built swim sets for targeted training

Beyond AI-generated plans, iSWIM offers a searchable library of individual workouts focused on specific goals — sprint speed, endurance, drill work, or race pace. You can build custom sessions by combining sets from this library.

Business outcome: Coaches and self-coached athletes can quickly assemble varied, purposeful sessions without designing them from scratch.

Social features for sharing workouts and competing on leaderboards

Users can share completed workouts, join challenges, and compare times on segment-based leaderboards. This introduces a gamification layer that helps maintain motivation for solo swimmers.

Business outcome: Increased user retention through social accountability and friendly competition.

• Structured AI training plansThe AI generates genuinely periodised plans that adapt to your performance, a feature rarely found in swim-specific apps.
• Wearable integrationSyncs seamlessly with Apple Watch to log workouts automatically, removing friction from data entry.
• Stroke efficiency analyticsProvides SWOLF and stroke rate metrics that help swimmers understand their efficiency, not just their speed.
• Affordable coaching alternativeAt $9.99/month, it is significantly cheaper than a human coach while still providing structured, personalised training.

• Limited to swimming onlyTriathletes will still need separate tools for cycling and running — iSWIM does not integrate with multi-sport training plans.
• No video analysisThe app cannot analyse your stroke technique from video, which is a key feature of human coaching and some competitors.
• Wearable dependency for full valueWithout a compatible smartwatch, you lose automatic logging and stroke metrics, reducing the app's utility significantly.
• Professional RealityiSWIM is excellent for structured planning but cannot correct your form in real-time — a limitation that matters for beginners with poor technique.

Triathlete building swim volume

A triathlete training for an Ironman uses iSWIM to generate a 12-week swim plan that builds endurance while balancing bike and run training. The AI adjusts volume based on fatigue from other sessions.

Masters swimmer returning to the pool

A former competitive swimmer returning after years away uses iSWIM to rebuild fitness safely. The AI starts with low volume and gradually increases intensity, preventing shoulder injuries.

Pool operator offering digital coaching

A community pool promotes iSWIM to its members as a free-value add. Swimmers can follow plans between coached sessions, increasing their pool usage and engagement.

Open water swimmer preparing for an event

An open water swimmer uses iSWIM to build a plan focused on endurance and pace control, with workouts that simulate race conditions using interval sets.

Download the iSWIM app from the iOS App Store and create an account with your swimming goals and current ability level.

Connect your Apple Watch or other compatible wearable to enable automatic workout logging and stroke analytics.

Complete your first AI-generated workout — the app will guide you through the set with interval timers and rest periods.

Review your post-workout analytics in the dashboard and let the AI adjust your next session based on your performance.
